TMPGEnc Audio Downsample Quality

[00Herb]

TMPGEnc Audio Downsample Quality is utter crap.
Any help appreciated.

[stanwebber]

i think it's acceptible, but try using ssrc for better results. tmpgenc is a front-end for ssrc, toolame among others

[00Herb]

Thx

Using same encoder with same problem.

Where can I find ssrc.exe, try'd Toolame same problem.

Tech. question whats the diffrence between the way tmpgenc and other external tools handle sound ?

Cheers all.

DVD2Avi 48 to 44,1 downsampling is also very good (ultrahigh) but damn slow.
If you use ssrc as an external converter through TMPG, you can not change the default settings except the samplerate. For more options use the commandline console or DanniDin's Azid_LameGUI.
Sorry for not having a tech. answer.

granted, having tmpgenc encode both the video and audio and then downsample will not be as good as external audio encoder, how is it crap?...if you used dvd2avi to extract the .wav file first, have you tried listening to the wav file first and comparing it to tmpgenc's result?

[Fatboy]

Had a listen to the dvd3avi wave file with headphones on, no problem with metalic background noise. But after encoding with TMPGnc yes same problem. Found and tryed ssrc seams to work ok will try more and post.
Q. Will TMPGEnc handle the audio any different if DVD2avi converts 48-44 before encoding. Or is the answer ssrc in TMPGEnc or encode audio externally and multiplex later ?

Tar..

The metallic sound which TMPGenc often produces is caused by the 48kHz->44100kHz conversion. If you do this conversion first in dvd2avi or ssrc then you shouldnt experience this problem. However, TMPGenc's audio encoder which converts wav to mp2, downsampled or not, is still noticably lower quality than other encoders. My advice is that when it comes to audio don't use TMPGenc for anything other than a front end.

48 to 44 is what's causing the lossyness? dang, I didn't think of that. Gah. >.< I'll just use Cool Edit to change the sound to 44 from 84 after extracting the wave.

hrm..weird.. i must be going deaf cuz i don't hear anything wrong with tmpgenc's audio downsampling at all....

[stanwebber]

i'm with you....unless people are being super-critical i must be missing something. that being said i still use ssrc though

[Fatboy]

Now try'd several films with ssrc. Shrek used to be the worst but with ssrc now ok.

Seams to erase most metalic after noise from sharp sounds.

I used to be a sound and light guy with a pop group and watching a film with a sound problem is ,,,, well off putting. But to most including poeple I've try to demonstrate to, its unoticable.

Will try external audio encoder and remuxing and post (unless anyone else has, and can offer advice).

Cheers Merry Xmas

SSRC at http://www.milky.ne.jp/~galaxy/ssrc/

SCMPX (which can also be used with TMPGEnc, and which I use if I'm batching or SSRC has a problem)

Ain't yahoo great.
